Ermes Sub Block Hard Pulley 5
Single block with two pulleys in Delrin, allowing the attachment of up to 5 rubbers for scaled inverted systems. This is a specially designed pulley system for neatly containing, organising multiple bands and allowing easy access for interchange of rubbers in invert-pulley roller spearguns.
They are openable and light weight. The body is laser cut from quality stainless steel and the pulleys are made from solid Delrin, without bearings. No bearings means low maintenance and eliminates the possibility of bearing failure.
These are useful to simplify attaching multiple bands and eliminate the added weight, length and complication of shackles.
